MANUR'E-SPREADER.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed January 3,1905. Serial No. 239,317.

To all whom it may concern.-

Be it known that I, FRANK W. HovEY, a citizen of the United States,residing at Independence, in the county of Buchanan and State of Iowa,have invented certain new and useful Improvements in Manure-Spreaders,of which the following is a specification.

This invention relates more particularly to the gearing which drives theapron of manurespreaders, and has for its object to produce a feed-drivefor such machines which is positive and powerful and adapted to suchvariations as to give any desired spread of said material on the ground.

The nature of the invention will fully appear from the description andclaim following, reference being had to the accompanying drawing, inwhich is shown a side elevation of a part of the rear end of amanure-spreader with my improved gear attached thereto.

In the drawing, A designates the body or box of a manure-spreader of afamiliar type, the bottom of which is an apron B, suitably moved forwardand backward, as by a polygonal wheel C on a shaft D. The body ismounted on a rear aXle E, driven by a supporting or traction wheel. (Notshown.) The parts at the other end of the machine are not necessary to acomplete understanding of this invention. The distributing cylinder F ismounted at the open rear end in the usual way.

Secured to the rear axle E is a gear G, meshing with a compound spur andbevel gear H, which turns on a stud I. On the same stud is mounted abearing J for one end of a shaft K, the other end having a bearing L ina casting IWI. On this diagonal shaft is mounted a series of gears N,varying' in size, so that their upper faces are practically horizontal,as shown. Parallel with these faces and journaled in bearings O and P isa shaft Q, carrying an adjustable pinion R, which may be secured at anydesired point along the shaft, as by a set-screw r. The pinion may thusbe slid to mesh with any gear on the inclined shaft at will and securedin mesh therewith. To the rear end of the shaft Q is secured a worm S,which engages a worm-gear T on the shaft D.

This construction is adapted to impart a positive, uniform, and steadyfeed, so that the manure is spread evenly on the ground. The quantity isvaried by simply shifting the pinion R to mesh with any desired gear onthe diagonal shaft.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The described drive mechanism for a manure-spreader, embracing,incombination with the feed-apron and its carrying-shaft and sprockets, aworm-gear attached to said shaft, a worm engaging' the same, ahorizontal shaft for the worm, with a slidable and adjustable spurpinion mounted thereon, an inclined shaft with differential spur-pinionsmounted thereon, a bevel-pinion on said shaft, a bevelgear engaging saidbevel-pinion, a gear engaging said bevel-gear and carried by one of thetraction-wheels, a casting adjacent to said gears forming a bearing forone end of the horizontal shaft, a bearing mounted on the bevel-gearstud to take one end of the inclined shaft, and a casting havinghorizontal and inclined bearings for the corresponding shafts at oneend, all substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
